Problems solved by technology

[0004] The purpose of the present invention is to provide a method for raising seedlings of submerged Sagittarius, which solves the problem that part or all of the bulbs need to be carried when raising seedlings of small bud type and small ball type Sagittarius, and the bulb tissue of some varieties is dense and cannot float. Arthia sativa seedlings with leaves can float in water. Stir with a rake to make them float to the surface and separate the arrowroot seedlings from the arrowhead bulbs; it can not only ensure that the leafy arrowroot seedlings surface in time to grow normally, but also can implement separate planting of large and small seedlings high yield measures

Embodiment 1

[0020] A method for raising seedlings of submerged type Sagittarius, comprising the steps of:

[0021] (1) Grading and screening the harvested submerged Sagittarius vulgaris by size, selecting small-sized sagittarius bulbs weighing less than 5g, and removing corms with no terminal buds or severely damaged terminal buds to obtain terminal buds with part or all of the bulbs It is the submerged type Sagittarius bulbs with green skin; or take out the stored bulbs; it corresponds to 2.5m per mu of Sagittarius field 2 The water surface of the seedling bed is selected as the ditch at the end of some ditches that do not affect the irrigation of the Sagittarius field. The ditches are cement anti-seepage ditches in the aquatic vegetable planting base. Pour into the ditch in turn, and leave the end of the ditch empty; the head of the ditch is cut off with nylon mesh or bagged soil; if the ditch width is greater than 1m, control the water level at 45cm; if the ditch width is less than 1m,...

Embodiment 2

[0029] A method for raising seedlings of submerged type Sagittarius, comprising the steps of:

[0030] (1) Grading and screening the harvested submerged Sagittarius vulgaris by size, selecting small-sized sagittarius bulbs weighing less than 5g, and removing corms with no terminal buds or severely damaged terminal buds to obtain terminal buds with part or all of the bulbs It is the submerged type of Sagittarius bulbs with green skin; or take out the stored bulbs of Sagittarius; it corresponds to 2.75m per mu of Sagittarius field 2 The water surface of the seedling bed is selected as the ditch at the end of some ditches that do not affect the irrigation of the Sagittarius field. The ditches are cement anti-seepage ditches in the aquatic vegetable planting base. Pour into the ditch in sequence, and leave the tail end of the ditch empty; the head end of the ditch is cut off with nylon mesh or bagged soil; if the ditch width is greater than 1m, control the water level at 55cm; if ...

Embodiment 3

[0038] A method for raising seedlings of submerged type Sagittarius, comprising the steps of:

[0039](1) Grading and screening the harvested submerged Sagittarius vulgaris by size, selecting small-sized sagittarius bulbs weighing less than 5g, and removing corms with no terminal buds or severely damaged terminal buds to obtain terminal buds with part or all of the bulbs It is the submerged type of Sagittarius bulbs with green skin; or take out the stored bulbs; it corresponds to 3m per mu of Sagittarius field 2 The water surface of the seedling bed is selected as the ditch at the end of some ditches that do not affect the irrigation of the Sagittarius field. The ditches are cement anti-seepage ditches in the aquatic vegetable planting base. Pour into the ditch in turn, and leave the end of the ditch empty; the head of the ditch is cut off with nylon mesh or bagged soil; if the ditch width is greater than 1m, control the water level at 50cm; if the ditch width is less than 1m,...

Abstract

The invention discloses a seedling culture method of sinking type arrowhead in the field of agricultural vegetable culture. The method includes the following steps of pouring arrowhead terminal buds with part of or all corms in one end of a ditch or sink so that the terminal buds can all sink in water, properly emptying the other end of a seedling culture area, conducting raking from the bottom and stirring once every 1-2 days after germinant seedlings float up according to the characteristic that leafing arrowhead seedlings are low in mass and can float on the water so that the germinant arrowhead seedlings can float up onto the water and be pushed to the other emptied end, making the arrowhead terminal buds not floating on the water retreat to the pour-in start end step by step when thearrowhead seedlings floating on the water are pushed, and lifting the seedlings to be transplanted into a large arrowhead field when the arrowhead seedlings grow to be higher than 30 cm. It can be ensured that the leafing arrowhead seedlings float up onto the water in time and normally grow, and the high-yield measure of separately planting large seedlings and small seedlings can also be taken.

Description

technical field [0001] The invention belongs to the technical field of agricultural vegetable cultivation, and in particular relates to a method for raising seedlings of submerged sagittarius. Background technique [0002] The Chinese patent database discloses a method for cultivating seedlings in Arthroatia facilities, its patent application number: 201210104119.4; application date: 2012.04.06; authorized announcement number: CN 102613055 B; announcement date: 2013.05.22; Flat furrows, the surrounding ridges are higher than the furrows; lay plastic film on the furrows and ridges to form a water storage tank; fill the water tank with clean water; pour the selected Arthia sativa top buds into the water tank, rake evenly, and make The terminal buds are densely floating in the water, and each terminal bud is partially submerged in the water and partially exposed to the water surface; a shed is erected on the flat border, and the shed is covered with a single layer or multiple l...
